Steel plates have a great ability to cover and accommodate, and can be used as roof panelsMaterials and manufacturing containers, oil storage tanks, packaging boxes, train carriages, car shells, industrial furnace shells, etc:It can be cut and combined according to usage requirements to produce various structural and mechanical parts, and can also be made into welded steel sections, further expanding the scope of use of steel plates;It can be bent and stamped to produce boilers, containers, stamped car shells, civilian vessels, appliances, and can also be used as a blank for welding steel pipes and cold-formed steel. Due to the above characteristics, the steel plate production reaches the total steel production50%The above.
In order to meet the needs of large-scale infrastructure construction, China's demand for steel plates has increased sharply. In order to meet the needs of the new situation, China's steel plate production has also made great progress in recent years, and a number of advanced steel plate production backbone enterprises have been established. Steel plates are supplied in sheets or rolls. The specifications of the steel plate are determined by its thickness*width*The length is expressed in millimeters. Familiarity with the specifications of sheet metal and strip steel, making full use of their width and length, is of great significance for improving material utilization, reducing inappropriate corner scraps, lowering labor hours and product costs. When selecting plates and strips, it is advisable to choose specifications that are multiples of the product blank. If it is a standardized product, when selecting plates or strips that are close to the fixed length, reasonable materials of fixed length or multiple length can be ordered, and the cutting method of nesting can be implemented to significantly improve the utilization rate of plates and strips. The repeated utilization of leftover materials between enterprises and industries is also an effective method proven by practice to improve material utilization and save materials.
Production process flow
